BACKGROUND OF THE INVENTION TECHNICAL FIELD Field of the Invention

The field of the invention is that of the food and beverages industryand more specifically food and beverages packaging.

Description of Related Art

There are several records of packaging that can be expanded in some way.

Within the automotive industry there are oil cans that incorporatefunnel-shaped appendages inside the body that help pouring oil moreprecisely.

The inventors are aware of the existence of some history of extensiblepackaging, including the following:

Spanish utility model ES0277689 for “Extensible container” with JaimeMorell Mestre as inventor, but after studying the file in depth, the wayto extend the container is done by means of notches outside the contentcontainer, a procedure totally different from that disclosed in thisinvention.

Likewise, the existence of the Spanish utility model, ES1055026,requested on Oct. 1, 2003, has been detected for “Extensible andhygienic device to ingest the content of soft drink cans and the like”.After studying the file, it is noted that it is a small spout-shapedextension located above the top of the soda can. Therefore, it hasnothing in common with the invention to be registered.

BRIEF SUMMARY OF THE INVENTION

The present invention, refers to an expandable container with a screwcap, like a soda can type, provided inside with a cylinder that allowsonce the cap has been removed, that said cylinder can emerge verticallycreating a new space, arranged to add another complementary liquid,another product, a piece of ice or simply to drink the liquid morecomfortably.

DETAILED DESCRIPTION OF THE INVENTION

The device described hereby incorporates a plurality of novel featuresin relation to other elements used within the sector and solves problemsthat until now were difficult to solve, in some cases impossible,

The present invention refers to an expandable container with a screwcap, being a soda can type of container, provided inside with a cylinderthat, once the cap has been removed, said cylinder can emerge verticallycreating a new space, ready to add another complementary liquid, anotherproduct, a piece of ice or simply to drink the liquid more comfortably.

The extendable container with screw cap is made up of a cylindricalcontainer, soda can type or similar, sealed at the bottom end and openat the top.

The container comprises a thread on its outer upper part that will serveto seal the container hermetically by means of a cap and inside saidcontainer there is a small flange along its entire perimeter.

The screw cap has an internal thread inside, to screw it to the externalthread of the container, and an elastic joint in its upper part, on theinside, which will make the assembly watertight when the cap is properlytightened. In this way, the container can contain all kinds of liquids,even gaseous or carbonated.

The extensible part is made up of a mobile inner cylindrical element,with a diameter slightly smaller than that of the container, which has astraight perimeter outer flange on its upper edge, which will rest onthe top of the container so that the cylinder is always attached whenthe container is closed and that it does not move and another flange onits lower edge curved towards the outside that supports the interiorwall of the container and that said curved flange has an elastic jointplaced on top it.

When the mobile inner cylinder slides upwards, it does so until theelastic joint located inside the lower flange abuts the lower part ofthe circular flange, leaving the assembly watertight in this area.

When the mobile inner cylinder is unfolded, the volume of the set isexpanded, so that to the liquid contained in the container you can addanother complementary liquid and even some ice, for example thinking ofa soft drink to which once opened you can add an alcoholic beverage andeven some ice. In this way, a glass will not be needed to prepare such acombination as it will be perfectly made inside the expandablecontainer.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The device proposed incorporates a plurality of novel features inrelation to other elements used within the sector.

The present invention refers to an expandable container, of a soda cantype, with a screw cap provided inside with a cylinder that, once thecap has been removed, said cylinder can emerge vertically creating a newspace, ready to add another complementary liquid, another product, apiece of ice or simply to drink the liquid more comfortably.

Specifically, the expandable container with screw cap is made up of acylindrical container (1), of the type of a soda can, closed at thebottom and open at the top.

Said container comprises on its outer upper part a thread (2) that willserve to seal the container hermetically by means of a cap (4) andtowards the inside a small flange (3) along its entire perimeter.

The screw cap (4) has an internal thread (5) inside, to screw with theexternal thread of the container (2), and an elastic seal (6) on theupper part of the inner part that will confer tightness to the assemblywhen the cap is properly tightened.

The extensible part is made up of a mobile inner cylinder (7), with adiameter slightly smaller than that of the container, which has astraight perimeter outer flange (8) on its upper edge, which will reston the top of the container (1), and another flange (9) on its loweredge curved towards the outside that supports the interior wall of thecontainer (1) and that said curved flange (9) carries an elastic joint(10) inside.

When the mobile inner cylinder (7) slides upwards, it does so until theelastic joint (10) located inside the lower flange (9) abuts the lowerpart of the circular flange (3), the assembly being watertight in thatarea.

When the mobile inner cylinder (7) is unfolded, the volume of theassembly is increased, so that to the liquid (11) contained in thecontainer another complementary liquid and even some ice can be added,increasing the volumetric level from level (13) to level (14).

Once the nature of the invention has been sufficiently described, aswell as the way to carry it into practice, it must be stated that theprovisions previously indicated and represented in the attached drawingsare subject to detailed modifications as long as they do not alter theirfundamental principles, established in the paragraphs above andsummarized in the following claims.
